Couldn’t update QT reference video

Asked By 30 points N/A Posted on -

I am having trouble exporting a QT Reference Video, after completing my short piece; I encountered this error message below. I have tried a number of tricks but I can export everything else apart from the stereo tracks. I am not sure of the next step, how can I fix this?

Assertion failed

An error has occurred:

Assertion failed: compDesc.acomp != NULL

You're presumably experiencing interweave problems. Either from associate operator error, or one thing is tamed the QT export method.

Check out this post (very long I am afraid). You will find all styles of data on completely different QT export processes and problems. Page two and ahead contains screenshots thus you'll compare along with your issue.

Check it link

Also be aware that typically issues apparent in Qt are going to be gone post secret writing.

Hope this helps.

Hello Shirleytjensen,

There is some sequence to do it. First of all, select a sequence in the browser, then

* Choose sequence > Setting.

* Hit Render Control Tab and adopt the appropriate rendering option for the output quality you want.

* Click Ok and apply the changes.

* You have to choose one from the following:

  • Set in and out points to define which portion of your sequence you want to export.
  • Clear in and our point to export the entire sequence.

* Choose File > Export > QuickTime Movie.

* Choose a location and enter a name for the file.
